Four vans were destroyed in an arson attack on a Borders business last Friday morning.
Cook’s Van Hire’s premises at Langbrae in Newtown St Boswells were targeted around 12.10am.
Detective constable Andrew Hope, of Galashiels police station, said: “The fire was started deliberately, and two vans were set alight, before the fire spread to a further two.
“This was a completely reckless thing to do as it’s destroyed the vehicles and damaged others nearby.
“If anyone remember seeing anything suspicious in the area around that time, please contact the police.”
Any potential witnesses are asked to call Police Scotland on 101 or Crimestoppers on 0800 555111.
